Jack's an Alliance military brat. His parents both served until they were killed in the line of duty. He had become a ward and was placed in a training academy where he enlisted after graduating and served dutifully until he faced a court martialed for refusing a direct order. Now with such a black mark hanging over his head, he seeks whatever work he can find.
Jack's an average looking guy that keeps himself fit and in shape cause his job demanded it... well, it did. He has blond hair and blue eyes and at his last physical he checked in at 5'10" and 180 lbs. He's got a little muscle but not much but is rather quick on his feet.
